Powerful Control in a Box

The PZ-Pre is equipped with two inputs for quick instrument changes on stage, or, for blending two pickups together.

Offering both pre and post EQ direct box outputs, the PZ-Pre can be used send a dry signal to the house and performer tailored sound to monitors.

PZ-Pre Applications

Using two acoustic guitars on stage

The PZ-Pre is the perfect stage partner for switching between two acoustics. You can have one for backup, alternate tuning or switch from 6-string to 12-string with ease.

Using upright and electric acoustic

Switch between contrabass and electric or acoustic bass with a simple foot stomp! The PZ-Pre's input is easily optimized to work with finicky piezo pickups for a deeper, more natural tone.

Using the PZ-Pre on violin and mandolin

Using the PZ-Pre with a piezo transducer will give you more gain before feedback than a microphone. You will be surprised at how good a piezo can sound when connected to a PZ-Pre!

    Joe West Demonstrates Radial's PZ-Pre


"It appears to have been designed by someone who has intimate knowledge of the problems faced by acoustic guitarists who rely on active or passive piezo-based pickup systems in their instruments... I can't think of any situation that I have come across on stage with my guitars that wouldn't have been dealt with by either the PZ-Deluxe or the PZ-Pre."

By Bob Thomas

"The most essential piece of Radial gear we carry is the Tonebone PZ-Pre acoustic guitar preamp."

By David Morgan

"The PZ-Pre's three-band tone control and notch filter, along with the low-cut switch, gave just enough flexibility to be useful, yet was still simple and straightforward enough to dial in a sound without having to tweak too much. The voicing of the tone controls was musical, smooth and relatively quiet, without a lot of unwanted noise or phasing issues."

By Phil Feser
